Study Drugs
Solanezumab and Gantenerumab
• Monoclonal antibodies that bind to beta
amyloid.
• Passive immunization.
• Modify early changes in the brain caused by
beta amyloid.
Side Effects
• Solanezumab given by IV or intravenous infusion
for 30 minutes you are observed for 2 hours after to
watch for side effects.
i. Anything unusual or usual you experience will be
documented
ii. Major side effects:
• Increased Water Content of the Brain tissue and
• Increase in Small Bleeds in the Brain Tissue
(micro-hemorrhage) Brain MRIs are required
every 3 months.
Side Effects
• Gantenerumab is given subcutaneously, just
under the skin on the abdomen. You are
watched for 2 hours after for any reaction.

Study Visits
• At Home Screening Visit (V01) screening
• Initial Baseline Visit (V02) screening and
Complete Assessment

Baseline Visit
At the baseline visit, the screening process will determine eligibility,
and biomarker studies completed. Specifically, you will be asked to
complete:
• A screening EKG
– to look for any cardiac (heart) abnormalities.
• An MRI
– which looks at the structure of the brain.
• Three PET scans
– scheduled over the entire visit. Each PET scan uses a small
amount of a radioactive tracer to observe either the energy
use of the brain or the presence of amyloid plaques.
• A lumbar puncture
– for collection of cerebrospinal fluid.
Baseline Visit continued:
• A clinical evaluation with a study clinician
– to assess for changes in memory and thinking,
judgment, personality and mood. The clinical will
also complete a physical and neurologic exam.
• Paper-pencil and computerized testing
– to assess your memory and thinking abilities.
• Blood sampling
– to determine if there are certain markers in the
blood (and if so how much) that might indicate
the presence of disease.
Baseline Visit continued
• Blood sampling for genetic testing.
– Your blood will be sent to a study approved lab
using a unique ID number to test for the reported
family mutation. You will not receive the results of
this testing. If, during your study participation, you
wish to learn your mutation status, the study
team will refer you to a certified genetic
counselor.

FAQs
• Weekend Treatments?
Yes we hope to negotiate weekend treatments.
• How long is the Trial?
The first part of the trial is two years. Depending on the
success of the drugs it may last longer.
• Can you tell if the drug is working?
Many of the side effects may not be unusual for you to
experience e.g. Headache and Nausea. Everything will
be reported to your nurse.
• Do you keep taking your regular medication?
Yes but the medication should stay the same.
FAQs
• When will trials begin?
The Washington University site has begun
recruitment.
• Do I participate at my DIAN Site?
Yes, preferably
